    But regardless of the method that is used, aluminum sand casting should result in a mold cavity being formed. These air set molds can be formed using a casting flask that has both a bottom and a top part.Next, the sand mixture is pressed together around the pattern of the mold cavity. The final part of the assembly will often require the sand to be vibrated in order to eliminate any holes or empty spaces in the mold. The casting liquid is ultimately what is poured into the mold cavity, and once the metal has cooled off and become solid, the casting can be finally divided from the sa......

    Aluminum sand casting is a metal casting process where sand is used to mold material together.Currently, a majority of metal castings are produced by the sand casting process. This is largely because aluminum sand casting is a very cheap and effective means of molding material together.Sometimes for increased durability, the sand will be mixed with clay. This mixture will moisten when added with water, and then strengthen when it dries afterward. This makes it much more suitable for molding.However, clay does not always need to be used for this method. Sometimes one method that is u......

    The process is generally used for small castings, but has produced complete aircraft door frames, steel castings of up to 300 kg and aluminum castings of up to 30 kg. It is generally more expensive per unit than die casting or sand casting but with lower equipment cost. It can produce complicated shapes that would be difficult or impossible with die casting, yet like that process, it requires little surface finishing and only minor machining.       Advantage- Can form complex shapes and fine details- Very good surface finish- High production rate- Low labor ......

    Drop Forging Manufacturer ProcessOur Forging machine press the metal blank to obtain the forging shape with required mechanical properties. Our forging presser is 560KG Air hammer, 750KG Air Hammer, 1T Air Hammer, 5T Air hammer, 2500T forging presser, etc Advantage of forging partsCompared with the same material casting process, forging process could eliminate the metal casting porosity, mechanical welding holes. So the forging parts are with much better mechanical properties than casting parts. The important parts with heavyload or applied in the rigorous condition, are produc......
